HDD Carrier Bracket with Moveable Frame Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standardized chassis sizes limit the arrangement and number of computing devices that can be mounted, particularly in 4U height chassis, where space optimization is needed to maximize the installation of hard disk drives and other devices.
Innovation Solution
The design includes a hard disk drive carrier bracket with moveable frame members and a tray assembly system that allows for the expansion and collapse of the bracket, enabling efficient use of space within the chassis, with multiple L-shaped slots and pins for secure mounting and easy installation/removal of hard disk drives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standardized chassis sizes are used, then manufacturing and compatibility are simplified, but the number of hard disk drives that can be mounted is limited
Solution Approach 1:
The bracket employs moveable frame members that can transition between extended and collapsed positions, allowing the mounting structure to dynamically adjust its configuration. This enables the bracket to accommodate HDDs in various orientations and positions within the standardized chassis, thereby increasing the number of drives that can be mounted without deviating from standard chassis dimensions.
Solution Approach 2:
The bracket is divided into multiple frame members (first frame member with first/second arms, second frame member with third/fourth arms) that can move independently relative to each other. This segmentation allows each arm to be positioned optimally for mounting individual HDDs, maximizing space utilization within the constrained standardized chassis volume.
2Stability of the object's composition
If fixed mounting structures are used, then structural stability is maintained, but installation and removal of hard disk drives becomes complex
Solution Approach 1:
The moveable frame members provide a dynamic mounting solution where the bracket can be easily configured during installation by extending or collapsing the arms as needed. Once the HDDs are mounted, the structure provides stable fixed positions for each drive. This dynamic-to-fixed transition during operation enables both easy installation and structural stability.
Solution Approach 2:
The moveable arms act as intermediaries between the fixed chassis structure and the HDDs. These arms can be adjusted to facilitate easy insertion and removal of drives, while when positioned and secured, they provide stable mounting. The arms mediate between the need for easy operation during installation and the need for stability during operation.
3Quantity of substance
If space is optimized for maximum HDD installation, then the number of drives increases, but the arrangement flexibility decreases
Solution Approach 1:
The dynamic moveable frame members enable the bracket to adapt its configuration to accommodate HDDs in different arrangements. The arms can be extended or collapsed to create various mounting patterns, allowing flexible arrangement of drives while maximizing the number that fit within the standardized chassis. This adaptability maintains arrangement flexibility despite the space optimization constraints.

AI summary
A hard disk drive (HDD) carrier bracket for use in mounting a hard disk drive (HDD) in a chassis via a HDD tray includes a first frame member and a second frame member. The second frame member is coupled to the first frame member such that the first and second frame members are moveable relative to one another, between an extended position and a collapsed position. The HDD carrier bracket is installable in the HDD tray without tools. The HDD tray is installable in the chassis without tools.
